2. Grafting: Generally, bud grafting and branch grafting are adopted. T-shaped and Z-shaped bud grafting are commonly used in bud grafting, and splitting, cutting and abdomen grafting are commonly used in branch grafting.
3. Cutting: on the Zanthoxylum bungeanum tree with fruit below 5 years old, select 1 annual branch as cutting. Cuttings can be soaked in 500 mg/L indoleacetic acid for 30 minutes, or in 500 mg/L naphthylacetic acid for 2 hours, or by hotbed rooting. The rooting rate and seedling rate of the treated cuttings are high.
4. Plant division: Before the pepper germinates in spring, tie the base of the 1-2-year-old tillering seedling around and bury it in the soil, so that new roots can grow from the peeled mouth. 1 After the growing season, the tillering seedlings can be separated from the mother plants and can be used for afforestation. Another method is to cut off 2/3 of the base of tillering seedlings with a sharp knife, and then cultivate the soil to take root. After the tillering seedlings are cut from the parent plant, they can be transplanted directly if the root system grows well. If the roots don't grow well, you can plant them in the nursery until the new roots grow more.
